This artificial heart is made from silicone

Researchers have developed an artificial heart made of silicone that beats almost like a human heart, according to new research from Eidgenössische Technische Hochschule (ETH). The ETH researchers set out to develop a heart that looks like the real time and functions like one too. It was designed by Nicholas Cohrs, a doctoral student in

Thomas & Betts says its cable ties resist microbes: Here’s how

Thomas & Betts (T&B) is touting its new Ty-Fast Ag+ bacteria-resistant cable ties, which it claims are the first that are able to inhibit the spread of bacteria. T&B (Memphis, Tenn.) – a member of the ABB Group – molded the cable ties from an FDA-compliant nylon resin blended with an EPA-registered antimicrobial silver ion

Lamborghini is helping to create better prosthetics

Automobili Lamborghini is collaborating with Houston Methodist Research Institute to bring its carbon fiber composite material expertise to prosthetic implants. The research that Lamborghini will be joining is a biocompatibility study of the composite materials that are used in prosthetic implants and subcutaneous devices. The goal of the study is to be able to determine

New biocompatible adhesive glues together soft tissues

Okayama University researchers say they’ve discovered a new type of biocompatible adhesive material made of hydroxyapatite that can glue together synthetic hydrogels and soft tissues. Adhesive organic materials instead of sutures join soft tissues. The method has been around for several decades, but it often has limited biocompatibility and sub-optimal adhesive strength. The researchers at

What startups need to succeed when selecting medical device materials

Whether a startup targets an emerging category such as wearables or a more mature device market, a well-planned approach to medical device materials selection can make a significant difference in the product launch cycle, economic model and other variables. Deepak Prakash, Vancive Medical Technologies Materials selection can be a make-or-break issue for medical device startups. Even

11 companies with interesting technology at MD&M East

Thousands of engineers and executives are expected to descend on the Javits Center in New York next week for MD&M East, the largest medical device manufacturing event on the East Coast. Fun attractions include Apple co-founder Steve “Woz” Wozniak delivering a keynote speech, the 19th annual Medical Design Excellence Awards, robot battles and a 3D printed

New CollPlant division focuses on 3D bioprinting

Regenerative medicine company CollPlant said Thursday that it has created a new division to focus on collagen-based bioprinting. CollPlant has been utilizing its proprietary plant-based rhCollagen technology for tissue repair. The new division will further develop collagen-based bioink for use in 3D printers creating organs and tissues. The Ness Ziona, Israel–based company says it has 3D

6 ways hydrogels are enabling medtech innovation

Hydrogels are water-based biomaterials developed specifically for human use, according to a Biomaterials journal article. They are a water-swollen polymeric material that doesn’t change its distinct 3D structure. They are formed from super-absorbent, chain-like polymers and are not soluble in water. However, their porous surface allows for nutrients and cell waste to pass through. They have

Aerospace may have something to teach medtech about materials: Here’s how

QuesTek Innovations has used advanced computer modeling to produce innovative materials in the aerospace sector. Now it’s looking to recreate the same magic in the medical device space. Chris Newmarker, Managing Editor Medical device developers typically turn to off-the-shelf materials and then design based on the properties of the materials. But does it have to

Gore’s Viabahn VBX: The very model of a modern major product launch

The Viabahn VBX built by Gore is the first and only balloon expandable stent graft with an iliac indication. It is a balloon-mounted, ePTFE-coated, stainless-steel stent. To deploy a physician accesses the artery and blows up the balloon, forcing the device to expand. The balloon provides radial strength while the stent it deployed, but also

New material illuminates when exposed to chemicals on the body

MIT engineers and biologists teamed up and designed a living-cell-injected hydrogel that can illuminate when exposed to certain chemicals. The MIT team made wearable sensors using the hydrogel with living cells that lit up after touching a surface with certain chemicals. The new material has the potential to detect chemicals in the environment and the

Metallic hydrogen could be a reality: Why you should care

Harvard University scientists say they have created metallic hydrogen, a super material that until now has only been theoretical. If the claims pan out, they could open up a host of possibilities, including in the medical device field. That’s because metallic hydrogen theoretically should be superconductive at room temperature. MRIs, for example, would no longer

Exploring ePTFE sutures for surgical product development

Zeus Industrial Products has developed an expanded polytetrafluoroethylene (ePTFE) suture based on physicians’ needs. In this podcast, Bruce Anneaux, corporate director of research and development at Zeus, reviews the material properties of Aeos ePTFE and the company’s latest offering, a suture monofilament. The structure of the Aeos material consists of solid nodes interconnected by a matrix of

Boston Sci giving lift to new erectile dysfunction device

Want to put some lead in your pencil? Try nitinol instead. The wonder metal—a nickel-titanium alloy with heat-activated shape memory—has proved essential for Wisconsin and Illinois researchers building what British tabloids are calling a “bionic penis.” Chuckles aside, the proposed implant has enough potential advantages over existing erectile dysfunction treatment implants that Boston Scientific officials
